To clean the Sipper, you should remove the glass bubbler and silicone inserts. Place the bubbler in a sealable plastic bag with isopropyl alcohol (iso), shake it, and use a pipe cleaner to clear any stubborn residue. Rinse and let it dry before use. Reinsert the silicone airflow valve properly. Clean the base of the sipper and the 510 connectors with a cotton swab dipped in iso, but make sure to wipe off any remaining iso to avoid damage.
